Product Description

The Concrete Self-Tapping Anchor Bolt embodies a revolutionary post-anchoring technology that delivers unparalleled anchoring power directly in concrete, thanks to its robust hard threads. Let's delve into the comprehensive analysis from multiple perspectives:

1, Core Features

1. Innovative Self-Tapping Anchoring Mechanism

Harnessing the might of high-grade, ultra-durable threads (typically carbon steel of grade 10.9 or above), this mechanism slices seamlessly into the concrete's hole wall, creating a secure threaded interlocking structure. No pre-drilling or chemical agents are required, and its formidable anchoring strength is evidenced by destructive tensile tests often culminating in the failure of the concrete itself rather than the anchor bolt.

2. Ingenious Reversible Installation Design

Facilitating easy disassembly through directional rotation modification, this feature is ideal for temporary fixtures like scaffolding and formwork support, resulting in substantial cost savings during engineering renovations.

2, Technical parameters and adaptability

1. Specification Matching Principles

The anchor bolt's diameter must precisely match the drill hole's diameter (e.g., M8 for 8mm holes), and various length models (such as 6 × 35, 6 × 55) are available to suit substrates of differing thicknesses, ensuring optimal anchoring depth to meet load-bearing requirements.

2. Material Performance Grading

• Basic Edition: Carbon steel of grade 8.8 or higher, perfect for standard environments

Enhanced Anti-Corrosion Edition: Constructed from 410 stainless steel with anti-corrosion treatment, designed to withstand extreme conditions like marine climates and chemical exposures.

High-Strength Edition: Grade 12.9 carbon steel, tailored for securing heavy equipment and use in seismic fortification zones.

3, Application Scenarios

1. Building Structural Reinforcement

Ideal for installing seismic supports and suspension systems within concrete beams, slabs, and columns, achieving rapid anchorage without compromising substrate integrity.

2. Equipment Installation

Perfect for securing curtain wall keels or mechanical and electrical pipeline supports, its minimal margin installation capability suits complex spatial configurations effortlessly.

3. Temporary Works

In settings like event venues or exhibitions, this anchor expedites the detachable securing of scaffolding and stage structures.

4, Technical Advantages

1. Unmatched Construction Efficiency

Installation time for each unit is slashed by over 60% compared to traditional expansion anchor bolts, with no waiting for adhesive curing.

2. Superior Bearing Capacity

In C30 concrete, a single anchor bolt boasts a tensile capacity of 8-15kN and a shear capacity of 5-10kN, varying by specification.

3. Exceptional Environmental Adaptability

With advanced materials, it withstands temperatures from -20 ºC to 80 ºC and boasts IP68 dust and water resistance.

5, Selection and Construction Points

1. Rigorous Substrate Evaluation

Evaluate concrete strength (preferably C25 or above), cracks (≤ 0.3mm), and steel density to prevent conflicts between anchor bolts and steel bars.

2. Precise Tool Matching

Utilize an electric wrench with torque control, maintaining installation torque within ± 15% of the nominal value for optimal results.

3. Stringent Quality Control

Post-installation, a sampling pull-out test is mandated, with a required bearing capacity standard of 1.5 times the design value.
